Telogen effluvium is an interruption to the normal hair growth cycle. Hair follicles enter the resting stage of the cycle simultaneously and there is consequently sudden hair loss. Causes are generally physical or psychological stress.
The stress may result from childbirth, major surgery, illness or any other reason. In addition, too much vitamin A can also trigger the condition, although this is only really likely via the intake of supplements.
Fortunately, the condition is not permanent. The hair follicles will reactivate, but it can take as long as eight months for hair loss to decrease and it will then obviously take a while for the hair to grow back. Hair loss is particularly noticeable when washing hair, but shampoo does not make the condition any worse.
As ever, the important thing to do is to get properly diagnosed by your GP or a qualified dermatologist. Knowing exactly what the problem is, you will be able to get the most appropriate treatment.
In cases where the person has suffered chronic telogen effluvium, management is possible through the use of scalp make-up, Medi Connections (ultra fine hair extensions) or hair replacement.
